To date, no studies have been reported that investigate the lower pole expansion resulting from varying tissue expander dimensions with objective computer software[15, 16]. The advent of three-dimensional imaging technology to objectively measure lower pole expansion provides a quantitative means to study the advantages of using the CPX3® tissue expander. We propose a study that will show whether or not the CPX3® tissue expander's unique design can have an ultimate effect on the shape and location of volume change on the postoperative breast. Three-dimensional cameras also provide an advantage for assessing patients undergoing bilateral mastectomy and reconstruction who desire a reconstructive outcome that will bear some resemblance to their current breasts [15].
